This sample displays a basic integer calculator powered by the 8051 microcontroller. Although Keil C51 has a full floating point math library the evaluation version is restricted to 2k of object code, so we have constrained this sample to integer maths in order to fit within this limit. The program for this design was written in C using the Keil uVision 2 IDE for which Proteus VSM provides a Debug Monitor driver. Instructions for configuring Proteus to run in conjunction with the Keil environment can be found by editing the 8051 microcontroller on the schematic (point at it and press CTRL-E) and then clicking on the help button on the Edit Component dialogue form.

The main features of the considered identification problem are that there is no an a priori separation of the variables into inputs and outputs and the approximation criterion, called misfit, does not depend on the model representation. The misfit is defined as the minimum of the l2-norm between the given time series and a time series that is consistent with the approximate model. The misfit is equal to zero if and only if the model is exact and the smaller the misfit is (by definition) the more accurate the model is. The considered model class consists of all linear time-invariant systems of bounded complexity and the complexity is specified by the number of inputs and the smallest number of lags in a difference equation representation. We present a Matlab function for approximate identification based on misfit minimization. Although the problem formulation is representation independent, we use input/state/output representations of the system in order

A Matlab toolbox for exact linear time-invariant system identification is presented. The emphasis is on the variety of possible ways to implement the mappings from data to parameters of the data generating system. The considered system representations are input/state/output, difference equation, and left matrix fraction. KEYWORDS: subspace identification, deterministic subspace identification, balanced model reduction, approximate system identification, MPUM.

就像在嵌入系統(tǒng)中使用C語言替代匯編一樣,在嵌入系統(tǒng)中使用RTOS是大勢所趨。原因主要是現(xiàn)在在大多數(shù)情況下編程效率比執(zhí)行效率重要（單片機(jī)便宜嘛）。但縱觀51的RTOS，keil c51 所帶的RTX Full 太大（6k多），且需要外部ram，又無源代碼，很多時(shí)候不實(shí)用。RTX Tiny雖然小（900多字節(jié)），但是任務(wù)沒有優(yōu)先級和中斷管理，也無源代碼，也不太實(shí)用。而ucosII雖有源代碼，但是它太大，又需要外部ram，所有函數(shù)又必須是重入函數(shù)，用在51這類小片內(nèi)RAM的單片機(jī)上有點(diǎn)勉強(qiáng)。于是，我借鑒ucosII和RTX Tiny編寫了Small RTOS 51,雖然它為51系列編寫，但是它還是比較容易移植到其它CPU上。

Get more out of your legacy systems: more performance, functionality, reliability, and manageability Is your code easy to change? Can you get nearly instantaneous feedback when you do change it? Do you understand it? If the answer to any of these questions is no, you have legacy code, and it is draining time and money away from your development efforts.
